Final answer:
The balanced equation for the reaction between nitrogen (N₂) and sodium (Na) to form sodium nitride (Na₃N) is N₂ + 3Na → 2Na₃N. The coefficients indicate the mole ratio required for the reaction to occur.
Step-by-step explanation:
The balanced equation for the reaction between nitrogen (N₂) and sodium (Na) to form sodium nitride (Na₃N) is:
N₂ + 3Na → 2Na₃N
The coefficients in a balanced equation indicate the mole ratio required for the reaction to occur. In this case, one molecule of N₂ reacts with three atoms of Na to produce two molecules of Na₃N.
